GEARING FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent No. 237,390, dated February 8, 1881.

Application led June 25, 188i). (Model.) l

To all whom it may concern:

Be it known that I, JACOB KING, of the city of Indianapolis, county of Marion, and State of Indiana, have invented an Improvement in Gearing for Grain-Drills, of which the following is a specification.

rlhe nature and object of the invention will be fully understood from the following general description and the accompanying drawings. i

Figure 1 of the accompanyingV drawings is a top view of part of a main drill with my device fastened on it. Fig. 2 is an edge view of the case in which my device is inclosed 5 Fig.

3, a sectional view of the same case with the" gear-wheels in it; Fig. 4, an `inside view of both halves ot' the same case; Fig. 5, a detail view of the ball-and-socket joint, hereinafter to be described.

In a case of cast metal of the form shown by e e of Figs. 2, 3, and 4. are placed four beveled wheels, r, o 0, and r. r and rare straight deep-cut beveled wheels. Vo and o are deepcut wheels, which are beveled bot-h ways with straight bevels. One part of this double bevel of o and o engages o and o together. The other part of `the bevel engages o and o with r and r, as shown in Fig. 3 of said drawings. 0 and o are mounted in straight rigid bearings in the case e e. r and r are Inounted in the case e c as follows:

At n or n there is a ball-and-socket joint. The ball is on the end of the axle, and forms the journal at the small end of the wheel r.

The socket is in the half e of the casel e e.

The other end of the axle of said wheels r consists of a straight journal, which is mounted in the slot rf, as shown in Figs. 3 and 4. Inl 'the center of each of these four journals is cast a square hole ot' convenient size, running` through the whole length of the axle.

At i and z' are square holes,.cast in said case to accommodate bolts for fastening said deof said case are secured together by convenient bolts, the whole device to be as shown in the drawings.

To use this device it is bolted firmly on one edge on the beam or central bar of a, graindrill, with the concave side e of the case forward. A shaft passes from a bevelwheel engaged by a bevel-wheel on the shaft of the driving-wheel to the square hole in the axle of one of the wheels o, and communicates motion to the entire train of wheels iuclosed in the case e e. Another shaft passes backward in the same way from the other wheel o to the feed-wheel of the middle grain-box. Another shaft passes in the same way backward from each of the wheels r and r, along'the wingbeams of the grain-drill, to the feed-wheels of the side boxes, so that when the drivin g-wheel begins to move not only does it communicate its motion to the train of wheels in the case e e', but also, by means of said shafts, to the feed-wheels of all three grain-boxes. It will now be found that the front ends of the shafts from the outside grain-boxes to the wheels r ,r as on pivots, and that, the other end of the axles ofthe wheels r and r being free to move a little laterally in theslots r and r', the side boxes and the beams on which they stand may be swung around laterally through an arc of several degrees without in any way aecting the working' of the machine; and thus, in drilling grain, the rows may be made wide or narrow, at pleasure. equally well in either position. The teeth of r,o o,and r are cut so deep that in any of said positions the lap will be sufficient for the work they have to do.

I do not claim to be the inventor of a balland-socket joint; nor do I claim the general use thereof 5 nor do I, for the purposes of this application, claim any of the devices claimed in Patent No. 138,166, which was granted to me on the 22d day of April, 1873, for an improvement in graindrills; nor do I, for the purposes of this application, claim any of the devices claimed in Patent No. 149,674, which was. granted to A. N. Norris on the 14thday of April, 1874,for an improvement in graindrills; but
